To all whom it may concern:

Be it known that l, ALBERT A. GERY, a citizen of the United States,residing in-the city of Reading, county oi Berks, and State haveinvented certain new fication.

My invention relates to the burning of brick or other material intunnel-kilns through which they are slowly progressed while beingsuccessively subjected to drying, heatin burnin and cooling treatment.in this method of burning, as fully described in my pendingapplications, Serial Nos. 228,128 and 230,091, the green material whichis periodically introduced at the entrance end of the tunnel isgradually dried and heated. as it progresses toward-the innertunnehwhere it is subjected to intense burning heat and is thengradually cooled it progresses to the exit end, the tunnel beingconstantly filled with material in difierent oi the burning treatmentand said. material being car ried upon a moving tunnel-floor, preferablymade up of a series of closcly-connecte l cars.

The main objects of my present invention are, first, to promptly andefiectivcly expel the moisture from the lower l; 'ers of incoming brickby heating the movable floor upon which they are carried; second, toabstract heat from the lower layers of outgoing brick by cooling themovable iloor in the outgoing portion oi the tunnel third, to reduce theexcessive heat beneath the movable floor in the inner tunnel; fourth, toutilize such heat for the first-mentioned purpose of indirectly dryinthe lower layers of incoming brick, and, fifth, to further utilise theheat-carrying current oi air directly in the incoming end of the tunnel.

The invention is fully described in connec tion with the accompanyingdrawings, illustrating a preferred i'neans of carrying the same intoellect, and is specifically pointed out in the claims.

Figure 1 is a "front elevation showing the entrance ends of twocontiguous parallel tun ncls with the last-entered loaded cars inposition therein, one of said cars being shown in cross-section and theend of the other show ing the subsurface longitudinal air-passagcsthcreol connected to the tunnel delivery airpipes. Fig. 2 is adiagrammatic plan view of the entrance ends indicating the arrangementof the air-pipes.

conducting air-pipes and s of the tunnels, further.

Fig. 3 indicates, partly in longitudinal section, a series of connectedfloor-sections traveling on car-tracks, together with the rayblast-pipe, communicating WltlD'LhQ'Sll surface air-passages in thefloor.

in carrying out my invention the carfioors 1, upon which the brick orother material is introduced to and passed through a tunnel 2 and whichjointly form the moving floor of the tunnel, are provided withlongitudinal air-passages 3 below the floorsurface, each arranged incommunication with those 'of adjoining floor-sections throughout theclosely-connected series within the tunnel to form a continuous passageor passages through the whole train. Atmospheric air is drawn into thesepassages through the lore- 1110851081 of the train at the exit end ofthe tunnel and flows rearward through the train, abstracting heat firstfrom the outgoing floor-sections and the cooling brick thereon andthereafter from the inner tunnel floorsections, upon which the burningbrick are piled, and carryingsuch heat to the entrance end of thetunnel, where it is in large measure imparted to the incoming floorsections, thereby indirectly heating the lower layers of brick piledupon said sections and insuring the prompt driving oil of moisturetherefrom, which is essential to the securing of uniform andsatisfactory results inall stages of the burning operation.

As shown in the drawings, the last-entered car of each tunnel series hasa connecting air-pipe 4 removallv attached to its rear end, so as toailord co1n.-nunication between the air-passages 8 of the connectedfloor-sections, and a fixed vertical air-pipe 5 on the tunnelface, whichlatter in turn communicates with a transverse pipe 6, connected in likemanner to each of, a group oi parallel tunnels. This pipe 6 leads to afan chamber 7, from which extends a "main blast-pipe 8, having alongitudinal extension 9 arranged along the face of the tunnels belowthe car-track 10. To this horizontal main at each tunnel a branch llastpipe is connected, com rising a vertical portion 11 an d a horizontaport'on 12, extending into the tunnel, the latter eing properly arrangedat such height as to permit the movable floor-sections to pass under it.This blast-pipe 12, as indicated, eitends into the tunnel and dischargesthe heated air into the drying brick carried upon the last-entered cars.This heated airis therefor.

preferably delivered in the form of a spraylast through suitableperforations or openings and serves the purpose of effectively carrvingthe moisture expelled from the bric to a stack or exhaust-fan (notshown) provided for removing it from the tunnel, as particularlydescribed in my pending applications referred -to.

To provide for conveniently introducing additional car-loads of materialar required,

each vertical portion 11 of the branch blastpipe is so connected to themain 9 as to perits being readily thrown out of the path of an enteringcar, this being effected,

indicated in the drawings, by connecting it to a turn-sleeve 13 on themain, which sleeve has an o ening for the branch pipe 11,

d to register with an outlet in the main only when the branch i e is invertical osition, the throwing o the pipe 11 out of the way thus servingto close said outlet. The horizontal spray blast-pipe 12 whendisconnected may lie upon the con- 'nected car-fioors,'the .brick beingso piled upon the latter as to provide a clearance-way Thus inintroducing a new car into the tunnelkiln both the vertical branch 11 ofthe blast-pipe and the connecting air-pipe 4 to the fioor-sectionlpassages are tempogreen brick so as to a single I tunnelrarilyremoved,but are reconnected when the new car 1s 1n positlon.

During the normal operation cool atmospheric air enters the connectedfloor-passages 3 at thQeXit end of the tunnel, traverses the wholelength of the train, successively abstiacting heat from the outgoing andinner tunnel-septions and imparting it to the incoming sections, and isthen drawn into the fan-chamber and finally discharged into the tunnel,the effect being, as already explained, first, to assist incooling theoutgoing brick; second, to carry off the excessive heat below theburning brick in the inner tunnel, and thereby reduce the heating of therunninggears and the discomfort of working below the same; third, toutilize such heat both indirectly-and directly upon the incoming insureprom tand thorough drying, particularly of the owcr layers of thelatter, and, finally, to hasten the burning operation and insure moreuniform and igh-grade rod not.

What I c aim is- 1. The improvement in continumisly drying burning and(:(mlingbrick and the like in a single tunl'iel-kiln which consists inproducinga current of air beneath the brick-supporting floor-surfacefrom the exit end thereto. to the entrance end, and utilizing saidcurrent to successively abstract heat from the outgoing floor-sectionsand to indirectly and directl heat the incoming brick.
